I'm currently using a Phanteks P300 with two 120mm intake fans (salvaged from a BitFenix Prodigy), and the provided Phanteks exhaust fan. I wish to replace the two intake fans, and potentially the exhaust in future.
My build is budget oriented, with a G4560 and a GTX 960, so I'm trying to get some good bang for buck fans. My budget is flexible, the ML140 fans at $60 NZD for the twin pack seemed like a good way to replace my intake fans on a budget. The Noctua NF-A14 fans are $40 NZD a pop, and 120mm Noctua fans are around $35 NZD each. Be Quiet! Pure Wings 2 are $20 NZD, Pure Wings 3 are $35 NZD. This is the site I use to search.
I would like to save money if possible, $30 NZD per fan seems reasonable. I don't need LEDs, I'm getting a Phanteks LED strip to fill that hole.
